Bed Struts again! Newtons

I've just discovered I don't understand newtons. The struts on our drop down bed are 2400n, when we've looked for replacements it says 1700n for a Hymer. We bought the van second hand so don't know if 2400n are the originals or have been changed before. The bed has been difficult to lift since we first got it so we are wondering if it has the wrong struts on. Does a greater pressure make it easier to lift or more difficult? Has anyone any idea what struts should be on a Hymer B524 please?

I would think it would be even harder with weaker struts - assuming they work in tension. A Newton is just a measure of force. The more Newtons, the greater the force. There are approximately ten Newtons to a kilogram on Planet Earth.

Thanks for going to the trouble Scotjimland. No they don't look the same. Ours have retainer star washers and the only way we can access them is from the windscreen end of the bed. Don't know if you can make sense of this.

From Jim's photo the strut works in compression, which is the opposite to what I guessed. Therefore the weaker 1700n strut should make the bed easier to pull down. But the OP's mechanism may be different. To check just look and see if the strut is shorter when the bed is pulled down.

We've had the struts replaced - this week - on our B640 after looking at the price of Hymer replacements, I opted for SGS - excellent service from them - the old struts were the originals put on in 1997 - the date was on them - the difference in the amount of effort needed to lift the bed is much, much better than I expected
